The mighty Ars Technica regularly takes on technically-intense reviews of processors and operating systems, but this time they’ve turned their attentions to something else altogether: DJ software. Dave Girard helms the review, with an exhaustive look at both basic DJ virtual decks (Disco, FutureDecks Lite, DJ1800) and full-featured software (VirtualDJ, Traktor DJ Studio from Native Instruments, and MixVibes Pro). (Thanks for the tip, Ryan Pollack!)

DJ Software for Windows and Mac OS X [Ars Technica]

The DJ apps get the full Ars Technica treatment, down to helpful figures explaining how DJing works for the uninitiated. Traktor DJ wins handily on Mac and Windows at the high end; for casual use on Windows VirtualDJ gets a nod. Girard also tests the hardware with the cheap Hercules DJ control surface / interface. This is exactly the kind of review from which I run screaming — round-ups are a total, life-sucking pain as a reviewer. (Yeah, I’m sure there’s a Logic 8 / Live 6 / Cubase SX 4 / DP 5 mega-review in my future, but in the meantime I’m going to try to keep enjoying life.)

The review also wins extra points for including an image of this business card. I wish Ashok had played my puberty party.

It’s a rare treat to see Ars doing DJ software, but there are some notable omissions.

One of the most sought-after devices this year is the R-09 portable recorder from Edirol. It’s got what everyone’s been looking for in an audio recording device: integrated mics, a gorgeous silver case with iPod-like, pocketable dimensions, SD cards for recording, rechargeable batteries you can actually replace when you need to, and some nice extras. The key question: will it fit people’s needs? You don’t want just one review; you want a whole bunch of reviews. And we’ve got them, from readers and authors all around the world who have been testing these recorders on sources ranging from acoustic music to barking dogs to interviews to ambient sound:
